Constructor Detail

SemaphoreConfig

public SemaphoreConfig()

Creates a default configured SemaphoreConfig.

SemaphoreConfig

public SemaphoreConfig(SemaphoreConfig config)

Creates a SemaphoreConfig by cloning another one.

Parameters:

config - the SemaphoreConfig to copy

Throws:

IllegalArgumentException - if config is null.

Method Detail

getAsReadOnly

public SemaphoreConfigReadOnly getAsReadOnly()

getName

public String getName()

Gets the name of the semaphore. If no name has been configured, null is returned.

Returns:

the name of the semaphore.

setName

public SemaphoreConfig setName(String name)

Sets the name of the semaphore.

Parameters:

name - the name of the semaphore

Returns:

the updated SemaphoreConfig

Throws:

IllegalArgumentException - if name is null or empty.

getInitialPermits

public int getInitialPermits()

Gets the initial number of permits.

Returns:

the initial number of permits.

setInitialPermits

public SemaphoreConfig setInitialPermits(int initialPermits)

Sets the initial number of permits. The initial number of permits can be 0; meaning that there is no permit. It can also be a negative number, meaning that there is a shortage of permits.

Parameters:

initialPermits - the initial number of permits.

Returns:

the updated SemaphoreConfig

getBackupCount

public int getBackupCount()

Returns the number of synchronous backups.

Returns:

the number of synchronous backups.

See Also:

setBackupCount(int)

setBackupCount

public SemaphoreConfig setBackupCount(int backupCount)

Sets the number of synchronous backups.

Parameters:

backupCount - the number of synchronous backups to set

Returns:

the updated SemaphoreConfig

Throws:

new - IllegalArgumentException if backupCount smaller than 0, or larger than the maximum number of backup or the sum of the backups and async backups is larger than the maximum number of backups

See Also:

setAsyncBackupCount(int), getBackupCount()

getAsyncBackupCount

public int getAsyncBackupCount()

Returns the number of asynchronous backups.

Returns:

the number of asynchronous backups.

See Also:

setAsyncBackupCount(int)

setAsyncBackupCount

public SemaphoreConfig setAsyncBackupCount(int asyncBackupCount)

Sets the number of asynchronous backups. 0 means no backups.

Parameters:

asyncBackupCount - the number of asynchronous synchronous backups to set.

Returns:

the updated SemaphoreConfig

Throws:

IllegalArgumentException - if asyncBackupCount smaller than 0, or larger than the maximum number of backup or the sum of the backups and async backups is larger than the maximum number of backups

See Also:

setBackupCount(int), getAsyncBackupCount()

getTotalBackupCount

public int getTotalBackupCount()

Returns the total number of backups (synchronous plus asynchronous); the returned value will always equal or bigger than 0.

Returns:

the total number of backups (synchronous plus asynchronous).

toString

public String toString()

Overrides:

toString in class Object
